Question

Ecuaciones cuadraticas 4x²- 20x=0 3x²-42=0 2x²-14x=0 8x²-98=0

Answer 1

Im so sorry.. I did not mean to submit an answer..

And I honestly don't know how to get rid of my answer.. but I will try to help.

4x²- 20x=0 = $x_{1}$ = -√5, $x_{2}$ = √5

3x²-42=0 = $x_{1}$ = -√14, $x_{2}$ = √14

2x²-14x=0 = $x_{1}$ = 0, $x_{2}$ = 7

8x²-98=0 = $x_{1}$ = -$\frac{7}{2}$, $x_{2}$ = $\frac{7}{2}$

I hope that these are the answers that you wanted, if they are not, I am sorry, tell me and I will try to fix them.
